Abstract
The main aim of this study was to determine antioxidant properties and antibacterial activity of monofloral bee pollen samples to pathogenic bacteria. These samples were collected in different localities in Slovakia. The antioxidant properties of examined plant species were different and decreasing in the following order: Brassica napus subsp. napus L > Papaver somniferum L. > Helianthus annuus L. The antimicrobial effect of the bee product samples were tested by using the agar well diffusion method. The methanol (99.9% and 70%) and the ethanol (96% and 70%) were used for extraction. In this study, five different strains of bacteria were tested: Listeria monocytogenes CCM 4699; Pseudomonas aeruginosa CCM 1960; Staphylococcus aureus CCM 3953; Salmonella enterica CCM 4420; and Escherichia coli CCM 3988. The most sensitive bacteria of the poppy pollen ethanolic extract was Staphylococcus aureus was (70%) The most sensitive bacteria of rape bee pollen methanolic extract (70%) and sunflower ethanolic extract (70%) was Salmonella enterica.
